  1. Office of Energy Research U.S. Department of Energy Office of Basic Energy Sciences William Oosterhuis Office of Basic Energy Sciences • Materials Sciences • Chemical Sciences • Geosciences • Biosciences • Engineering Sciences Serving the Present, Shaping the Future

  2. Improvements in Quality of X-ray Beams 1) Development of Wigglers and Undulators - Increased Intensity and Brightness - Experimental Facilities R & D 2) Increased Brightness - Better Focussing of Electron Beams - Beam divergence and cross sections reduced - Accelerator R & D (reduced emittance) 3) Increased Electron Beam Current - Improved RF Systems, Electron Guns - Accelerator R & D 4) Improved Electron Beam Stability (Accelerator R & D) - Control of Mechanical Vibrations - Improved Orbital Feedback Systems - Thermal Stability to maintain orbits
